Vibe coding has a genuine superpower: it lets developers follow instinct, collapse the feedback loop, and discover the shape of a problem by building against its edges. But the creative high has a shadow side that often goes unacknowledged. This episode of DEV.co explores the case for keeping humans central to vibe coding — not to slow it down, but to keep it from quietly going off the rails.Here's what the episode covers: What vibe coding actually is — improvisation as a development

Reactive programming on Android means choosing how your app handles asynchronous data — and for most teams, that choice eventually comes down to Kotlin Flow or RxJava. This episode of DEV.co digs into the practical differences between the two libraries, drawing on the Kotlin Flow vs. RxJava comparison article to give developers a clear framework for making that call. Whether you're greenfielding a new app or inheriting a legacy codebase, the tradeoffs are more nuanced than "new vs.

Your students are halfway through a unit, and you need to know whether they actually understand what you’ve taught. Should you grade them now, or should you use the information to adjust tomorrow’s lesson? This episode explains the crucial distinction between formative and summative assessment through a realistic classroom example. You’ll learn how to recognize each type even when the Praxis avoids explicitly naming it.

A student becomes anxious every time the teacher announces a quiz, while another starts turning in homework because doing so earns extra computer time. Both behaviors involve learning, but they illustrate two very different types of conditioning. In this episode, we distinguish classical from operant conditioning and apply both concepts to realistic classroom situations. You’ll also learn the reinforcement-versus-punishment distinction that commonly causes confusion on teacher exams.

Monolithic iOS codebases have a way of growing quietly out of control — slow builds, tangled dependencies, and features bleeding into places they were never meant to go. This episode of DEV.co tackles the problem head-on, drawing on this guide to Swift Package Manager and modular iOS architecture to lay out a clear, practical path from chaos to clarity. Whether you're starting a new project or migrating years of legacy code, the principles here are grounded in how real teams actually ship

Budgeting for a new website in 2026 means navigating a landscape that AI has genuinely disrupted — but not in the way most people assume. This episode of DEV.co examines the real breakdown of website design costs in 2026, separating the hype from the concrete shifts that affect what you should actually plan to spend. Spoiler: the total budget doesn't disappear. It redistributes.Here's what the episode covers: Baseline costs haven't collapsed. A professional informational site still
